The investigation on properties of sodium sulfate-activated mortar incorporating steel slag with various replacement ratio and particle size

The alkali-activated materials are alternatives for replacing Portland cement to manufacture concrete products, which has benefits on reducing carbon dioxide (CO2) emission and supporting the development of green sustainable construction. The combined use of steel slag (SS) and alkali activator (AA)...
